### 2.4 Type-of-Service

Applications MUST select appropriate TOS values when they invoke transport layer services, and these values MUST be configurable. Note that a TOS value contains 5 bits, of which only the most- significant 3 bits are currently defined; the other two bits MUST be zero.

DISCUSSION:

  As gateway algorithms are developed to implement Type-of- Service, the recommended values for various application protocols may change. In addition, it is likely that particular combinations of users and Internet paths will want non-standard TOS values. For these reasons, the TOS values must be configurable.

  See the latest version of the "Assigned Numbers" RFC [INTRO:5] for the recommended TOS values for the major application protocols.
